A paving binder classified by needle penetration at 25°C. Lower values indicate a harder binder and higher values a softer one; selection also depends on the specification, climate, traffic and mix design. For an enquiry, share the required penetration range, applicable standard and intended asphalt layer. Review the full test profile rather than choosing on the grade name or price alone.
Reference limits from the SRNT catalogue, not measured batch results or a COA. Availability, the applicable standard edition and contractual limits are confirmed for each enquiry.
